YARN-CLEANING DEVICE.

Application filed April 28, 1922. Serial No. 557,067.

T 0 all whom it may concern:

Be it known that we, WILLIAM A. BARTON and ANDREW A. DE Lewis, citizens of the United States, residing at Chattanooga. in the county of Hamilton and State of ,Tennessee, have invented certain new and useful Improvements in Yarn-Cleaning Devices; and we do declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an yarn cleaning from over-sized knots, bunched places caused by husks or by obstructions. If these knots, enlargements and other obstructions which are known in the art as slugs are not removed, a poor grade of yarn is the result and therefore after the yarn has been spun, it is to be run from the quill onto a windingcone and while passing from this quill to the winding comb will be engaged by this cleaning device which is called a guide and the slugs will be removed. In order to remove the improperly tied knots and obstructions in the yarn, there are devices which are now in use, one of which is a simple contrivance and consists of a flat surface over which the yarn is caused to pass. This flat surface or plate extends in front of a guide and the plate may be raised or lowered so as to adjust the space between the guide and plate to the proper size to permit a thread to pass between them. A weight is placed on the plate in front of the guide and the thread passes under this weight so that it is kept under tension.

In some mills a guide of a better grade is made use of and consists of a comb of steel teeth set above a spindle bar and at such distance from the spindle bar as to permit the improved thread to pass over the bar and under the device for use in cleaning yarn.

improper spinning and other properly tie the The objection to these guides now in use is that they either have a hole through which small knots and slugs may pass or the comb is so attached that it may be raised by simply placing a strip of paper or other material behind the comb. This work is done on a piecework basis and therefore an operator who desires as little breakage as possible will place the thread to run through the larger opening or raise the comb so as to let the knots and slugs pass. Therefore, the thread will notbe properly'cleaned and an inferior grade of thread. will be the result. With this device the guide bar which also constitutes the comb is so mounted that it can bereadily adjusted for threads of different sizes and is moved by means of a setscrew having a countersunk head for en gagement by a key which will be retained by the superintendent or other official in charge. Therefore, the guide bar cannot be tampered with by the operator and knots and other obstructions which should be removed cannot be allowed to pass through the device. It will be further noted that the thread when approaching the device will be allowed to run loose and thus permit it to have an oscillating motion which will throw the thread against the teeth of the comb and thus give a comb a better opportunity to remove any foreign matter from the thread.

This improved yarn cleaning device is illlustrated in the accompanying drawings, wherein:

Figure 1 is a view showing the device in SlClQGlGVfltlOH and mounted for use.

Figure 2 is a top plan view of the improved device.

F 1gure 3 is an enlarged view showing the device in front elevation.

Figure 4 is a sectional view taken line 4 4l of Fig. 2.

Figure 5 is a sectional view taken along the line 5-5 of Fig. 2.

Figure 6 is a perspective view of the guide bar and comb.

This improved yarn cleaning device is provided with a base plate 1 which may be termed the body portion and is provided with a transversely extending passage 2 through which a rod 3 will extend to permit mounting of the device, a set-screw 4 being provided to engage the rod 3 and securely but releasably hold the device in the proper position upon the rod. This base plate or body portion 1 may be rectangular in shape I 7 1fdeslred or may be cut away as shown in dental'l'y detachec lation' to each other.

This thickened portion is provided with a threaded socket 6 which emanate-m the up oer face otthe base .plate and receives the threaded lower enchportion of the stem or pin 7. This stem or pin 7 extends upwardly from the base plate and has its free end portion bent to provide a'sidefarni 7 I to prevent the 'diskB which constitutes a weight trornbeing caused to jump oft ot the It wilL-thus be seen that the disk or weight, 8 will be permitted of free movement upon the pin but cannot become acci-,

I Guide arms 91 extend TIl'QTnf/he forward edge of the base plate 1 and as show vn in Fig. 2 extend in flaring re- 1 I It will thus be seen that the thread l0 passing from the quill 11 te a suitable winding conemay be passed between these arms 9ian d pern iitted to have limited movement along the base plate. Theretere,,this thread will engage with the combined comb and guide bar in a very efliclent manner. v I v w r The guide l2eXteI1dsalong the upper face er base plate 1 one end portion provided with openings 18 to receivepins 14 carried by the base plate '1. From an inspection of ig. 4:,it will be seen that when put in place, these' pins/14 are passed throughopenlngs formed in the base plate and have their upper end portions exthis bar relative through the openings 13 of the guide bar 1'2' I These pins fit tightly in the openings of the base plate sothat. they do not have movement relative to the base plate but are suffi'ciently loose in theopenings 13 to p cally. In order to provide means for holding guide bar in engagement with the base ,plate and provide for adjustment of to the base plate, there has been provideda screw 15 having its shank portion provided adjacent the head of the bolt Withleft-handthreads as shown at 16 i n' Fig. 4, the free end portion (if the shank of this bolt being reduced and provided with thus be seen that the reduced portion of the shank may be passed through the threaded opening 18 of the guide barand the por- 'The reduced end pore bo'lt can then 'b'e'screwed into *theth'readed opening 19 of the basep'late.

' Afterthe fbolt has been put in place; the

pits 14 will be inserted and thejguide bar will be prevented 'trorjn having rotary move- "went; view of the fact that the portions 55 'lfi and 17 o-f'this bolt are oppositelythreadserving as means I ermit the guide bar to be moved vertiguide bar moves vertically away from the base plate until it contacts with the head of the bolt and prevents further rot'ation of the bolt. When the bolt'is rotated to move the guide bar from the plate, rotation o'l the bolt is stopped as soon as the guide bar contacts with the upper face of the "plate. It will. thus be seen that the boltcann'o't be ent'i'rely removed while the pins 14 are in place. By having the headot the boltcountersunk in a socketformed in 'the guide bar at-the upper end'ot th threadedope'ning 1'8,

the'bolt cannot be turned by means of an ordinary wrench or pair otpli'ers. A-suitable turning key will be provided which will be retained by the superintendent. foreman or other official in charge, and'there'fo re when the guide bar 'is se't5it's position cannot be changed without permission of the 'oflicial in charge. It is of course understood that if desired, the head of the bolt 15 instead of being enlarged could be reduced and pro"- vided with'fiat faces or could havea key receiving-socket formed in its upper end. The end portion-of this guide barwhich extends between the arms 9 and the weight 8 is hollowed out as shown-at 2'1 thus roviding spaced forward and rearwall portions for 'the'ba'r. The front wars Shaped. as shown in Fig. 5 and is out "to-provide teeth as shown thus providing iafcomb 22. A slot 28 is formed in'th'e base plate beneath the hollow end portion .of the so that when ltflS desired to cleanthe teeth of the comb,xthe guidewbar' can bemoved upwardly itsfull; extent throughthe medium of the screw 15 and the teeth-of the comb portion thoroughly cleaned. v a

-When this deviceis in use, itis'set up upon the rod 3 and secured inthe desired position by means of the set screwlt. The thread 10 is then passed between. the arms to provide 'thecombI After being passed beneath the guide bar, the threadis'p'assedbeneath the weight and then carried over the rear-edge of the base plate to; asuitable winding (zone. The guide bar can be set at the proper distance away fromgthexupper face of the base plate either'before 'oriafter the device is put in place =u'p.on:-theirod 3 and will of course be properly adjusted according to the size of thread which riswto be cleaned. In View of the factthat the portion of the thread between'the quill. 11 and the device-is not under tension, thisthrea'd will be left free :tohave movement between guide bar 12 the arms 9 and therefore it will have a tendency to move longitudinally of the guide bar and pass between any of the teeth. The weight is free to move about the stem or pin 7 and therefore it will serve to place the portion of the thread between the device and the winding cone under the proper tension, it will not interfere with the proper feeding of the thread to the winding cone. This weight cannot readily move off of the pin due to the bent portion 7 but when de sired it can be easily moved off of this pin by simply being lifted upwardly and turned at the bend. When a portion of thread reaches the guide bar which has not been properly tied or has become lumpy, this portion will catch in the teeth of the comb or between the guide bar and base plate and the thread will be broken. The operator will then break out the imperfect portion of the thread and after feeding the thread through the guide will properly tie the broken ends together.

We claim:

1. A yarn cleaner comprising a base plate, a guide bar upon the upper face of the base plate having one end portion provided along one side with comb-forming teeth, the base plate having a threaded opening formed therein and the guide bar having a threaded opening registering with and larger than the opening formed in the base plate and having its threads cut in opposed relation to the threads of the opening in the base plate, a bolt screwed into the threaded opening of the guide bar and having a reduced and oppositely threaded portion screwed into the threaded opening of the base plate, and pins passed up through the base plate into openings in the guide bar upon opposite sides of the bolt.

2. A yarn cleaner comprising a base plate, a guide bar upon the upper face of the base plate having one end portion provided along one side with comb-forming teeth, the other end portion of the guide bar being provided with a threaded opening, means for vertically adjusting said guide bar rotatably carried by said base plate and having a threaded portion extending through the threaded opening of said guide bar for imparting vertical movement to the guide bar when rotated, said means including means for engaging said guide bar and limiting upward movement of the guide bar, and means for preventing rotation of said guide bar when said adjusting means is rotated.

8. A yarn cleaner comprising a base plate, a guide bar upon the upper face of the base plate having one end portion provided along one side with comb-forming teeth, a bolt screwed into a threaded opening formed in the other end portion of the guide bar and beneath the guide bar reduced and oppositely threaded and screwed into a correspondingly threaded opening in the base plate, and means carried by the base plate and engaging the guide bar to permit vertical movement and prevent turning movement thereof.

In testimony whereof we have hereunto set our hands.
